The 'Safe Haven' star had left the gems inside her car in the parking lot when she visited a friend in Hollywood on March 8, TMZ reported.
The former 'Dancing with the Stars' regular drove a Mercedes and parked it in the lot, leaving three pieces of jewelry inside the car. When she's back a few hours later, her car's door was allegedly wide open and the inside was ransacked.
There was reportedly no visible signs of forced entry, but it's still unclear whether the 'Footloose' actress left the door unlocked or not.
